type NullableString = string | null | undefined;

type NonNullableString = NonNullable<NullableString>;
// type NonNullableString = string;

const str1: NullableString = null;
const str2: NonNullableString = 'hello';
const str3: NonNullableString = null; // Error: Type 'null' is not assignable to type 'string'.
